Request failed – Ensure firewall outgoing port is opened and ensure domain can be resolved.
The most common reason for this error is that your WHMCS server is unable to communicate with the MediaCP due to the outgoing port 2020 being blocked from your WHMCS server.
We recommend you follow the below steps:
-
Check MediaCP is up to date with most recent version to ensure compatibility.
-
Check the WHMCS server Hostname, Port & SSL Mode exactly matches with your MediaCP installation
-
Check OUTBOUND firewall port 2020 is on the WHMCS server, or contact your hosting provider to complete this.
-
Test the MediaCP API connection using our online testing utility. If the API test is successful then the issue is with your WHMCS server firewall. If the API test is not successful, then please contact us with the output information for further troubleshooting.
